## What this repository is — an open-source legal AI skill library

A **legal AI skill** is a single Markdown file (`SKILL.md`) that describes one
applied legal task — *«calculate the German court fee under the GKG for a
civil claim», «analyse this case under FRCP Rule 12(b)(6)», «check this DPA
against GDPR Article 28»* — in a structured format an AI agent can execute
deterministically.

Skills follow the [Anthropic Skills convention](https://www.anthropic.com/news/skills):
YAML frontmatter (machine-readable contract) + Markdown body (the algorithm).
Every skill in this repository is grouped into a plugin by **jurisdiction**
and **practice area**:

```
{country}/{practice}/skills/{slug}/SKILL.md
```

Allowed `{country}` values: any ISO 3166-1 alpha-2 code, plus `general`
(jurisdiction-agnostic) and `cross-jurisdiction` (multi-country comparative).

**There are two ways to use these skills:**

1. **Locally.** Since this repository is open source and every skill follows the
   Anthropic Skills/plugin format, you can clone it and use the skills locally
   (as Claude Code skills/plugins).
2. **Via the MCP server ThomasMore.** Connect any MCP-compatible
   client to the MCP server `mcp.thomasmoreai.com`; the orchestrator finds and
   runs the right skill via its `discover` and `invoke` tools. Follow
   [thomasmoreai.com](https://thomasmoreai.com/) for updates on the MCP server launch.

## FAQ

### Can I use these skills with Claude, Cursor, ChatGPT, or other clients?

Yes. The skills are delivered over the **Model Context Protocol (MCP)**, which
is supported by Claude Code, Claude Desktop, Cursor, ChatGPT (via MCP plugins),
the ThomasMore desktop app, and any other MCP-compatible client. Point your
client at `https://mcp.thomasmoreai.com/` and the orchestrator handles
discovery and routing. Follow [thomasmoreai.com](https://thomasmoreai.com/) for 
updates on the MCP server launch.

### Are these skills production-ready?

The repository is **community-curated**. Every skill carries an explicit
`version`, `author`, and `license`, and is reviewed against the schema
before merge. Output of every skill includes a built-in disclaimer that the
answer is informational and does not replace qualified legal advice. Treat
the library as a **second pair of eyes**, not as a substitute for a lawyer
admitted in the relevant jurisdiction.

### Why not just write a prompt myself?

Skills are versioned, testable, and citation-disciplined: each `SKILL.md`
specifies which statutes, regulations, or cases it relies on (and which
edition / date). Ad-hoc prompts drift, hallucinate citations, and aren't
reproducible across team members. Skills make legal AI workflows
**auditable** — important for compliance, conflicts checks, and post-mortems.

### How do I add a skill for my jurisdiction?

If your country code (ISO 3166-1 alpha-2) is missing, just create the folder
— e.g. `pt/contracts/skills/...` — and open a PR. See [CONTRIBUTING.md](CONTRIBUTING.md).
